Description

Technical Field

[0001] The present application relates to the technical field of injection molds, and in particular to an injection mold for automobile plastic products. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. It offers fast production speeds, high efficiency, automated operations, a wide variety of designs and shapes, and the ability to accommodate a wide range of sizes from simple to complex. Furthermore, it produces precise product dimensions, is easily updated, and can produce complex shapes. Injection molding is suitable for mass production and complex-shaped product molding.

[0003] Injection molding is a method in which a completely molten plastic material is stirred by a screw at a certain temperature, injected into a mold cavity with high pressure, and then cooled and solidified to obtain a molded product.

[0004] The Chinese invention patent with application number CN201710155806.1 discloses an injection mold, which includes a fixed component, a movably arranged ejector pin component on the fixed component, and at least one ejection mechanism. The two ends of the ejection mechanism are respectively connected to the side walls of the fixed component and the side walls of the ejector pin component. The fixed component accommodates a slider assembly and a core assembly connected to the slider assembly; the ejection mechanism includes a telescopic component and an elastic component connected to the telescopic component. The elastic component is accommodated in the fixed component. The telescopic component is provided with at least one protrusion. When the core assembly is ejected, the ejector pin assembly drives the elastic component to move, and the elastic component abuts against the protrusion.

[0005] In the prior art, after the production of the finished plastic product is completed, the mold needs to be removed to clean the mold cavity. When removing the mold, the mold is released, and the multiple top plates and templates in the mold are taken out in turn and brushed by the operator, or the top plates and templates are soaked after being taken out.

[0006] With respect to the above-mentioned related technologies, when removing the top plate or template, the top plate or template will tilt during the removal process, and the tilted top plate or template will interfere with the installation column, so that the top plate or template needs to be constantly adjusted to reduce the possibility of interference between the top plate or template and the installation column, which makes it inconvenient to remove the mold and difficult to clean the inside of the mold.

The cam is provided with a plurality of support members, each of which is connected to the support member and the support member is connected to the support member.

[0010] By adopting the above technical solution, the support assembly is installed according to the size of the mold to be dismantled and cleaned. If the mold is large and heavy, three or more support assemblies are installed. When disassembling the mold, after sliding the slide to the appropriate position, first use the locking member to fix the connecting rod, then adjust the guide column so that the side wall of the guide column is in a fit state with the side wall of the mold, and finally use the locking bolt to fix the guide column to facilitate the tight guidance of molds of different sizes; start the lifting member, and the lifting member lifts the top plate and the template from top to bottom in turn. The lifted top plate and template are fixed in turn using the fixing assembly. When the lifting member lifts the top plate or template, the top plate or template slides up along the height of the guide column, reducing the possibility of the top plate or template being stuck with the top column in the mold due to tilting when removing the top plate or template, thereby facilitating the disassembly and assembly of the mold; a cleaning gap is left between each two adjacent top plates or templates, and the cleaning gap facilitates the operator to clean the template and the inner cavity of the template.

[0011] Optionally, a first fixing member is provided on the slide, and the first fixing member is used to fix the slide in the slide. A first waist-shaped groove is provided on the base near the first fixing member, and the long side direction of the first waist-shaped groove is parallel to the long side direction of the base.

[0012] By adopting the above technical solution, the first fixing member fixes the slide, thereby improving the stability of the slide in the slide groove, thereby improving the stability of the support assembly, and further improving the stability of the lifting member when lifting the top plate or template.

[0013] Optionally, the slide is detachably connected to the support column.

[0014] By adopting the above technical solution, when the thickness of the mold is large, the support column can be replaced according to the thickness of the mold.

[0016] By adopting the above technical solution, the initial state of the lifting plate is to be located on one side of the mold. When lifting the top plate and template in the mold, the first drive lifts the second drive until the second drive can drive the lifting plate close to the gap of the top plate or template to be lifted, and then start the second drive. The second drive drives the lifting plate to turn to the gap of the top plate or template to be lifted until the lifting plate is inserted into the gap of the top plate or template to be lifted, and then start the first drive again. The first drive drives the second drive to lift, thereby driving the top plate or template on the lifting plate to lift, and after lifting to the appropriate height, the top plate or template is fixed.

[0017] Optionally, a guide plate is arranged between the second drive and the lifting plate, and the guide plate is rotatably connected to the second drive. A slider is provided on the side wall of the guide plate near the support column, and a sliding groove is opened along the height direction of the support column near the slider. The slider is located in the sliding groove and can slide along the sliding groove.

[0018] By adopting the above technical solution, when the second drive is lifted, the guide plate is lifted together with the second drive. When the guide plate is lifted, the slider slides along the slide groove, pulling the second drive when the second drive is lifted, reducing the possibility of damage to the second drive when lifting a heavier top plate or template.

[0019] Optionally, one end of the lifting plate is fixedly connected to the second drive, and an end of the lifting plate away from the second drive is provided with a spike end.

[0020] By adopting the above technical solution, the spiked end facilitates the lifting plate to be inserted into the gap of the top plate or template that needs to be lifted.

[0021] Optionally, the fixing assembly includes two fixing half frames, which are symmetrically buckled along two supporting columns, and the two fixing half frames are detachably connected, and a receiving plate is provided under each fixing half frame.

[0022] By adopting the above technical solution, when fixing the lifted top plate or template, the receiving plate is placed under the fixed half frame so that the top plate or template fits with the receiving plate, and the two fixed half frames are fixed, so that the two fixed half frames are clamped on the support column to receive the top plate or template, which is convenient for fixing the top plate or template.

[0023] Optionally, a second fixing member is provided at one end of the connecting rod close to the supporting column, and the second fixing member is used to fix the rotation angle of the connecting rod.

[0024] By adopting the above technical solution, after the length of the connecting rod is adjusted and fixed, the rotation angle of the connecting rod on the support column is adjusted again to further fix the two support columns, thereby improving the stability of the support columns and thus improving the stability during disassembly and assembly of the mold.
